Two-stage centrifugal compressor, high efficiency, more stable

The two-stage centrifugal compressor is not easy to surge; the system economizer supplies air between the compressor stages, and the cooling capacity is increased by at least 10%.

Intelligently judge the surge area, adjust the speed and IGV in time, avoid the occurrence of surge, and make the operation more stable and safer.

Gear speed-increasing drive, the impeller volume is smaller, the motor starting torque is small, and the downtime is short.

The motor is integrated with the compressor, and the running noise is low, and there is no risk of leakage.

The motor is cooled by liquid refrigerant, with low operating temperature and high efficiency.

Use high-strength ball/roller bearings, not afraid of compressor emergency stop.

Water cooling centrifugal chiller DC inverter motor, high energy efficiency and energy saving

Perfect oil circuit system, safer and more reliable

Using an independent oil return system (ejection pump oil return), it can ensure timely oil return under any load conditions.

The unit has built-in oil cooler, which is cooled by refrigerant, which is safe and reliable.

The oil pump is built into the compressor oil sump, eliminating the risk of oil pump leakage.

High-efficiency heat exchanger for water cooling centrifugal chiller with excellent performance

High energy efficiency heat exchanger with excellent performance

The use of self-developed and produced high-efficiency spray heat exchangers, and the use of precise liquid level control technology, ensures that the evaporator is always in a high-efficiency heat exchange state.

The condenser adopts droplet separation technology to ensure high energy efficiency and sufficient heat exchange of the condensing heat exchange tube.

COP value up to 6.3

Water cooling centrifugal chiller magnetic levitation oil-free technology, energy saving and noise reduction

With heat recovery device, free hot water

Using self-developed heat recovery device, the waste heat generated in the refrigeration process is recovered. While providing customers with cold water, a large amount of hot water can also be supplied free of charge.

Water cooling centrifugal chiller condensing heat energy recovery, free and practical

Environmentally friendly refrigerant with good overall performance

The mainstream environmentally friendly refrigerant R134a is used, which has good comprehensive performance, and the ozone depletion value (ODP) is 0.
